Beyonce's album sales have fallen by over 70 percent in the last month and it could be down to what she said about non-black people.

The former Destiny's Child star revealed in an interview with Blender magazine that she only made music for black people.

"I make black records. I write records like I speak, and I don't try to change my songs so everyone else likes them."

Knowles was booed at the recent MOBO Awards in London when she failed to turn up to receive any of the three awards she was due to collect.

The precocious star won Best Video, Best Overseas Performer and best Single for Deja Vu.
